This .invention relates to paper foldinag, machines, and more especially paper fol ing machines of that type having a folding cylinder of size to accommodate two papers,

5 and in object is to produce an attachment for fo ding machines of the character mentioned, for efficiently stacking the papers or sheets alternately in two distinct or separate places. It is desirable to accomplish the purpose mentioned as it makes provision for the printing and folding of two different papers upon one running of the press due to the fact that the different or alternately printed or folded papers are segregated from each other in a rapid and efiicient mannor. It effects a material saving in getting the presses ready for operationand 1n the labor cost attendant'on preparing the makeread and in the operation of the press. vMy special object is' to provide an attachment for a folding machine of any standardtype,-that shown being known in the market as the Goss type,-without making any change in the operating mechanism of the 2 folder except to substitute for the ordinary fixed guide or switch, an oscillatory guide or switch, and the provision of the extra features or attachments for cooperation with such oscillatory uide or switch to convey every alternate s eet to and-dispose it at a point different from that at WhlCh the other sheets are disposed. Another object 1s to provide an attachment of simple, strong, durable and inexpensive character.-

With the objects named in view, the invention consists in certain novel and useful features of construction and combinations of parts as hereinafter described and claimed; and in order that it may be fully the accompanyin'g drawings, in which :'-v I Figure 1 is a. fragmentary view of the [folding part of a 'prmtin press, equipped v.with a construction .em dying my m vention.

- Figure 2 is a top lan view of the convence to Fi modationof two papers, and 3 the customary cutting cylinder for .cooperative action with respect tocylinder 2, and of one-half the circumferential area of the latter. In a regulation folder of the Goss type, the paper in folded conditionis fed between rollers 2 and 3 and is automatically pinned to the former in a manner common in the art and thereforenot shown or described in this connection. In the rotation of the cylinder when theopposite edges of the paper have attained the horizontal plane of the axis of the cylinder, the aper' 1s cut b the cutting rol er and a lade descen s through cylinder 2 and creasesthe paper at its central point so as to start,the foldin thereof, the blade descending so as to fee the folded edge'of the paper between the customary feed rollers 4 and '5 underl ing i the cylinder. The blade mentioned an the mechanism for operating it are conventional in paper folders and have not been illustrated or described as they form no part of the present invention.

At a suitable distance below and journaled in the sides of the frame work 1 is a rotary fly 6, the same operating in the direction indlcated by the adjacent arrow, in Figure 1, through mechanism conventional and therefore not shown or described: In the conventional folder there is a fixed guiding means for directing all of the papers as they successivel .pass downward between feed rolls 4 an 5, to the fl 6, so that the same' may either stack such papers or deposit them upon a traveling conveyor or the like, now shown. In lieu of each of such fixed guides, I have provided an oscillatory guide; or switch 7, thesame beingpivoted inthe frame work 1 and extending upward so that its upper or receivin end may stand at one side or=the other 0 the-line of travel be-; tween the feeding rolls 4 and 5. By. refer:

re 2 it will be noted that the roll 4 is ofsectional character, being shown as of three sections spaced apart sufficiently to permit the upper extremities of the guides or switches to project between them when the former occupy one limit of. movement. Thecompanion roll 5 may be of. similar construction, but is shown with reduced diametric portions 8 between thesections for the accommodation of theup r ends of the switches when at the other imit of opera tion. A link 9 pivotally i connects each I}? switch with a crank of a shaft 11 suitably journaled, and said shaft is provided at a with a roller 21 engaged by a cam 22 rigidly secured. on-the shaft ofthe cylinder 2, so that once in each revolution, saidcam shall im art downward movement to the slide bar an thus efiect operation in one direction of the switches 7. In the interval between the depression of the slide bar by the cam, the former isre-elevated by a spring 23 fitting around a rod 24 pivoted at 25 to the slide bar and extending through a guide opening 26, of guide 19, the spring bearing at its lower end upon said guide 19 and its 11 per end against a collar 26 secured on ro 24, which collar, in the downward movement of the slidebar effects the compression of the, spring necessary to provide for the reaction P whereby the slide bar is re-elevatedthe switches 7 returned to normal or initial position. Should it be desired to secure the switches against operation so that all of the papers sha l he passed in the same direction,

a set screw 27 is mountedin the guide 20,

and the slide bar is provided with a hole 28, through which the set screw can be advanced for the urpose of holding the guide bar depressed and therefore the roller 21 out of range of movement of the cam 22.

For the purpose- 0f, deflecting or guiding papers issuing from between the feed rollers 4 and 5 so that they shall not pass to the fly 6, each switch is provided with a laterally projecting arm 29, so that when the switches occupy the position; shownb the full lines,

' Figure 3, the papers will be eflected laterally under roll.;5, a nd between a pair of endless tapes or conveyors. 30 and 31, the former atone end engaging reduced portions 32 of roll 5, and at their opposite ends engaging roll 33, suitabl supported At an inter mediate point t e upper strands or runs of tapes 30, underlie a guiding roll 3d, =;and betweenthe same and roll.33,. and above the horizontal plane of both, said .upper strands engage tensioning rollers 35.

The lower strands of .tapes -30; fiie flatly upon the up or strands or runs pita 31, which at their lower ends engage r0 ers 36 underlying roll 5 so that in conjunction with -''-the adjacent portion of tapes. 30," a flaring mouth willbe provided for the reception of sheets deflected thereinby the arms 29 of the switches, The upper ends of tapes '31 engage roller 37, and aroundsaid roller and itssta es o31, the lowerstrands of tapes 30 exten the arrangement being such that 37 and discharged downwardly in proximity to roller 33, there being tension rollers 38 engaging tapes 31 to hold the same in stretched or tautcondition. The sheets as they are discharged by said tapes are guided by a fixed guide or switch 39 into asuitably driven fl 40, and they'are suitably stacked by the atter, preferably upon a suitably driven conveyor 41.

' From the foregoing, it will be apparent that sheets are alternately directed y the switch 7 onto the fly 6 and between the cooperating tapes 30 and 31, the cam 22 by positive application of power swinging the switch 7, in each revolution, from one side of the line of travel between the feed rolls 4 and 5 to the other side of such line of travel, and the spring 23 reversing this position of the switch-in the same revolution. The result is that the papers are alternately fed to the flies 6 and 40 with celerity and efficiency, this so regation being desirable of course only w "ere two diflerent papers are being rinted and folded in one run of the press. To provide for take-up due to wear of parts in practically constant operation when different pa rsare being segregated, a lug an projects om the frame work and carried a stop screw 43 adjustable to limit the upward movement of arm 16.

,From the above description and draws it will be apparent that I have produced a machine which accomplishes the objects set forth as desirable in the statement of the objects of the invention, but that it in sunce tible of modification in minor particulars without departingffrom the principle of construction and mode of operation involv' lit will
